HMC855LC5

v02.0614

28 Gbps, 1:4 DEMUX

w/ PROGRAMMABLE OUTPUT VOLTAGE

The HMC855LC5 is a 1:4 demultiplexer designed for

data deserialization up to 28 Gbps. The device uses

both rising and falling edges of the half-rate clock to

sample the input data in sequence, D0-D3 and latches

the data onto the differential outputs. A quarter-rate

clock output generated on chip can be used to clock

the data into other devices. The demux is DC coupled

supporting broadband operation.

All clock and data inputs to the HMC855LC5 are CML

and terminated on-chip with 50 Ohms to the positive

supply, GND, and may be DC or AC coupled. The

differential outputs are source terminated to 50 Ohms

and may also be AC or DC coupled. Outputs can be

connected directly to a 50 Ohm ground terminated

system, or drive devices with CML logic input. The

HMC855LC5 also features an output level control

pin, VR, which allows for loss compensation or signal

level optimization. The HMC855LC5 operates from a

single -3.3V supply and is available in RoHS compliant

5x5 mm SMT package.

The circuit board used in the application should use

RF circuit design techniques. Signal lines should

have 50 Ohm impedance while the package gro-

und leads should be connected directly to the

ground plane similar to that shown. The exposed

metal package base must be connected to Vee. A

sufficient number of via holes should be used to

connect the top and bottom ground planes. The

evaluation circuit board shown is available from

Hittite upon request. Install jumper on JP1 to short
